CPD2 / 20 Mine Portable Barometer is a portable instrument specially designed for mine ventilation test. It can not only measure the absolute absolute pressure value in the local area, but also measure the pressure difference between two points. It has the characteristics of high precision, high sensitivity, reliable structure and intrinsic safety. The whole instrument is light weight, easy to carry, not afraid of general vibration and collision, stable and reliable performance, is an ideal underground ventilation test instrument. Explosion-proof mark is ibl (150 ℃) Technical index · Range: ± 200 mbar (absolute) ± 500 mm water column (relative) · Resolution: 0.1 mbar (absolute air pressure measurement) 0.1 mm water column (relative differential pressure measurement) · Applicable elevation range: -1500 ～ + 2500 meters (selected in seven steps) · Accuracy: 0.5 mbar (calibration period of three months) 0.1 mbar (on-site calibration) 1 mm water column (relative pressure difference measurement) · Display: 3 1 / 2-digit LCD digital display · Temperature effect: 0.01 ~ 0.02 mbar / ℃ (absolute air pressure measurement) 0.1 ~ 0.2 mm of water column / ℃ (relative air pressure measurement) · Vibration resistance: the instrument does not show changes in collision or vibration under normal use Greater than 0 ～ 0.1 mbar (absolute air pressure measurement) 0.1 ～ 0.2 mm water column (relative differential pressure measurement) · Environmental conditions: temperature -10 ～ + 40 ℃ temperature <90% · Power supply: using nickel-isolated alkaline storage battery pack (12V) , It can work continuously for more than 24 hours after each charge for 4 hours. · Appearance: 140 × 130 × 190mm3 · Weight: 3Kg
Note: Select instruments with consistent performance to be sold in groups, which can basically eliminate the influence of temperature in the measurement of relative pressure difference
